The journey is 223 kilometres (139 mi) one-way, taking almost five hours. There are 16 tunnels and four viaducts, with the Staircase Viaduct elevated as much as 75 metres (246 ft).

The New Zealand DJ class locomotive is a type of diesel-electric locomotive in service on the New Zealand rail network. The class were built by Mitsubishi Heavy Industries and introduced from 1968 to 1969 for the New Zealand Railways Department (NZR) with a modernisation loan from the World Bank to replace steam locomotives in the South Island, where all of the class members worked most of their lives. Nine of the locomotives remain in use, mainly with Dunedin Railways.
